show the approximate surface area under conditions of average annual maximum
fluctuation, and at the practical minimum level.
Under periods of drouth, the reservoir could be drawn down to the level
of the power penstocks to meet downstream water commitments. This condition
would result in a water level fluctuation of 195 feet.
The photo below shows the area being cleared of vegetation to provide
a debris free shoreline up to 170 feet of fluctuation.

The following description of reservoir operation was taken from a re-
port prepared by the Utah Fish and Game Department entitled "The Lnpact of
Flaming Gorge Unit upon Wildlife Resources in Northeastern Utah". This pro-
jected reservoir operation was derived from hyrdological data and graphs
for a 29 year period provided by the U. S. Bureau of Reclamation, Salt Lake
City, Utah.
"The plan of reservoir operation indicates that in most years
the water level will be gradually lowered beginning in January.
A steady drawdown of the reservoir will continue into late April
or early May. Just prior to the spring run-off the reservoir
will generally reach its lowest level of the year. During the
period of high spring run-off, the reservoir will rise rapidly,
and by the latter part of July will have reached its highest point.
From early August to the following January, the water level will
remain relatively constant, as inflow into the reservoir is
balanced by discharges."
